I've recently upgraded to Ubuntu 17.10 and tried the new version of openmw, and unfortunately saw this, after turning on the water shader: http://i.imgur.com/UhOVN92.png

After searching a bit, I've found this thread, with user experiencing the very same problem: viewtopic.php?f=2&t=4095 that seems to experience the same problem and that is dependency on libpng12. The newer Linux distributions sadly don't have this library in repositories any more. Is there any remedy?
